OEM/ODM welcome.FAQWhat steel grades are used in your gate steel accessories?We use Q235B and Q345B carbon steel for standard gate accessories, and 304/316 stainless steel for corrosion-critical applications. All raw materials come with mill certificates. Structural components such as weld-on hinges and drop bolts are manufactured from Q345B for higher tensile strength.What surface treatment options are available for gate steel accessories?Available treatments include hot-dip galvanizing (HDG, ASTM A153, 85 µm min), powder coating (Akzo Nobel, 60–80 µm, any RAL color), electro-zinc plating, black oxide, and self-color (raw steel). HDG is recommended for outdoor applications; powder coating is preferred for decorative finishes.Can you supply gate steel accessories in custom sizes or configurations?Yes. We accept custom orders for gate wheels, drop bolts, cane bolts, and gate stops in non-standard sizes. Provide your drawings or specifications and we will quote accordingly. Custom orders typically require a minimum of 200–500 pieces and a lead time of 25–35 days.Do your gate steel accessories meet international standards?Yes. Our gate accessories are manufactured to comply with EN 1527 (hardware for sliding gates), EN 12604 (industrial, commercial, garage doors), and AS 1170 (Australian structural standards) where applicable. Test reports and compliance documentation are available upon request.How do you ensure consistent quality across large production runs?We operate under ISO 9001:2015 quality management. Each production batch undergoes incoming material inspection, in-process dimensional checks, coating thickness measurement, and final load testing. We provide full QC reports with each shipment, and third-party pre-shipment inspection (SGS, BV) can be arranged.What material and finish options are available for the SB-40x40 corner brackets?The SB-40x40 corner brackets can be manufactured from carbon steel, stainless steel, or aluminium depending on your load and environmental requirements. For carbon steel variants, we offer electro-zinc plating for standard indoor furniture applications, as well as hot-dip galvanizing and powder coating for superior corrosion resistance on outdoor gates or windows. We can tailor the material grade and surface treatment to meet your specific project specifications for any order meeting the 10,000-piece MOQ.Do you offer OEM/ODM services to customize the hole patterns or dimensions of the SB-40x40 corner brackets?Yes, we provide comprehensive OEM and ODM services for our corner brackets, allowing you to specify custom hole configurations, material thicknesses, or alternate dimensions. Given the standard MOQ of 10,000 pieces, we can efficiently adapt our stamping dies to produce your exact design in carbon steel, stainless steel, or aluminium. Simply submit your CAD drawings or technical requirements, and our engineering team will supply a rapid tooling quote and production timeline.Request a quote from HST
